The search module is used to search through the database for a set a keywords with the results delimited by a set of constraints.
 When first loaded, the search page will display a form with the following fields:
</p>
<ul>
<li>Select search time frame</li>
<li>Time frame 1</li>
<li>Time frame 2</li>
<li>Select prescribed date or test date</li>
<li>Keywords</li>
<li>Sort By</li>
</ul>

<p>
The search time frame is determined by the first three fields. If 'All' is selected in the time frame selector, then the search will return 
results from all times. If 'Before', 'After' or 'On' are selected then only the 'Time frame 1' field is used and the results will be limited
to being before, after or on the date specified in 'Time frame 1'. If 'Bewteen' is selected, then both time frame fields are used, and only 
the results between these two times will be added to the search results.
</p>

<p>
The next option tells the search whether it should be searching by the prescribing date of the test, or by the date the test occured.
</p>

<p>
The keywords field requires a set of keywords to search for. These keywords can be any word found in either a patients name, a record's
description or a record's diagnosis. These keywords are comma delimited. 
</p>

<p>
Lastly, the sort-by selector allows the user to sort the results by the defualt ordering, most recent or least recent.
</p>

<p>
When the submit button is clicked, the search is then sent to the database and the results are printed in a table under the form.
